My sister has one of the new 11" MacBook Airs running 10.7, and recently got an external DVD drive in order to watch DVDs on it.
Most films work fine but there are a couple that when opened in DVD player, do nothing (the timecode just says 0:00), and when opened in VLC just crash it!
These DVDs work fine on my machine (MBP running 10.8), both in the internal disc drive and in her external disc drive.
Does anyone have any idea why these certain DVDs wouldn't work on her machine with the external player but work fine anywhere else?
The only obvious differences between our machines I can think of are that hers has USB 3 ports (I believe), mine doesn't, and she runs 10.7, I run 10.8. Is there a chance that upgrading to 10.8 could fix it?
Any help would be appreciated.
